Just read that the water supply of the Rochefort Brewery is threatened by mining operations. A facebook campaign to support the Trappists was started and is waiting for some likes:https://www.facebook.com/tridaineAlso a more official looking petition can be signed here:http://www.tridaine.be/Unfortunately everything is in french, but I think you'll be able to find your way around these sites.

Lhoist operates quarries which exploit a sizable deposit on the Gerny plain, situated on top of the spring. The watertable for the source begins at 211 meters below the surface, and the proposed permit would allow expanding the quarry to a depth of 220 meters.

In 2008, Lhoist experimented with pumping that caused the spring to dry up. This is why Lhoist informed the abbey of their project to extend the quarry below 211 meters. The abbey has categorically objected to any additional exploitation: Hands off the Tridaine spring!
